To all whom it may concern;

Be it known that I, Fnnnrn mn E. KA FF- MANN, a citizen of the UnitedStates, a resident of Hal way, county of Union, and State of New Jersey,have invented certain ne n ul Improv ments in Mach ne for Fi ing th g sref Hat B ms, e hi h t e ll i s is a pe ifiestieh- This inventionrelates to an improved nn,- chine for treating the edges of hat; brings,and is particularly adapted for treatingthe edges of the brimsof velourhats. n A p n t ehet brim s et lene its edges by the usual device, whichconsists of a knife on a gage, by means of which the distance from thecrown of the hat is regueted, h e y e ge of he im she t the vbody ofthe. hat and the soft furry appearance of the rest of the hat is miss ngfrom th dge f the br m A umb r of war ve b e e i ed to e er eme t s, onebein a; inakethh b i al t e t iekx ess hi the hat body, but twice itsnormal width, and hre ded h a er y e h hly n i and hen ding thi ove withe fu ry side out to form the hat brim, but this method isunsatisfactory and expensive, I have devised a machine which treats, theedge o t brim so t a the s ep o e h e l se im nate and h h brim i g venth prope id h d els e proper e ge a ra'e a'lly the a e ime, and itrequire lint wone action by the machine, and when t ha is mo ed a rem hma hi e th edge of the brim is at the required distance fro the cro andha t e s m appea a e as the rest of e h The invention is illustrated inthe accomp'ehyihg a in s, in whie Figu e 1 s. a fr Vi w, s a par s eingbro n awe-y, thi V w s sa rm f y mpseved machine.

A hrhsh 8. is r t t by th shaft h eh is drivenby the tb'eltBO and pulleys '31 and 32 from the shaft 16. The belt 30 iscrossed and the belt 25 is not, so that the brushes 23 and 28 arerotated in opposite directions. p e p The gearing of the brushes is suchthat p p g V high rate of speed compared With the speed of the rotationof the hat. The shaftsj-fitand 29 are mounted in stand ards which areconhected, as at 34, so that they I nove:together and are mounted in asuitable jsupport fii these standards, which has 2 Whiehi-erms a damp, bing I willca'll hesupport, being slid-able in the hase85, which base isfastened, as at 36, to "the standard 10 and is held thereon againstrotation. I

yielding means, such as the weight .37, tends, through the cable '38, topull the supplort, and consequently the brushes, toward t e hat untilthe support 33, by means of its arm 89, engages, through the roller 40.the cam 4i on the hat support, This cam 41, as will he seen from Figure2, is somewhat elliptical to conform to the shape of the hat c'ro'wnfsothatvas the hat rotates. the brushes are retreated "or are advanced,according to Whether the broader or the narrower part of the hat ispresented to the 'brushes. A handle 42 is provided whereby the brushescan he retreated away from the hat brim, which is i' f ahl Weigh (endhehg e ha dl in advance of these a shredder 15.

desirable, for instance, when the hat is to be removed and a new hat putin position. Belt tighteners 4:3 insure the belts 25 and remaining tightwhile the brush support is at its various positions.

In order to shortenthe. time necessary to reduce the hat brim to therequired size, I

provide, in addition tothe brushes 23 and 28,

slightly more rigid elements to act on the hat first. The brushes 23 and28 are made of very fine wire, and in advance of the brush 23 I preferto arrange heavier wires 44, and It will be seen from Figure 2 that thehat is first engaged by the shredder 45 which has teeth 46 thereon andwhich is made usually from a thin disk of metal, and the teeth,rotating'at fa high rate of speed while the hat rotates slowly,successively pull from the hat small particles, then the carding wiresle will fur- 'ther cut down the amount or material and then the finebrushes 23 and 28, one rotating in one direction and one in. the other,fiufi' the material, so that when completed, the edgeot' the hat brim,shown at 47 in Figure 6, has the same appearance as the rest or the hatand none of the body or the hat is pre- -sented to view.

1 of the operator is-not impaired by reason of this hair and these furparticlesfioating in The method of operation is to place a hat on thehat support and then deposit the flange 21 on it. The machine is put inoperation by a suitable clutch, whichis not shown f and which can be ofthe ordinary stop type which will operate the machine for, say,tworevolutions otthe hat and ,then automatically stop. This deviceyis'notshown as it forms no. part ofthis invention and isan ordinary article ofcommerce. As the hat rotates, the rapidly revolving shredder and thebrushes cut down the diameter of the brim slightly, as will be seen.from Figure 2,and

' after the hat has made two full revolutions the edge of the hat brimis finished. 1 prefer to normally have the brushes 23 and 2301 slightlylarger diameter than the carding wires 44 and the shredder 45.

"In Figure 7 I show a modified form of hat support in which the weightedpart 21 can I be eliminated, in this construction the flange 12 having ametal strip 51 which is connected by wires 52 with a source ofelectrical energy, and a light metal hate-lamp '53'is put in place-auditholds 'the hat brim down by. reason or" its attraction to the-magneticring 51.

1111 FigureS I show-a modified form or brush, this brush 54 beingarc-shaped and being pivoted, as at 55, and reciprocated by a suitablemechanism,.such as the arm 56, so that the single brush will operate tofiufi or brush the fibre of the hatin both directions. This reversal ofdirection is preferred, because if the fibre is brushed all in onedirection it causes a semi-permanent lay of the fur in one direction. I

A still further modified forn'ror' brush is shown in Figure 9, the brush57 being of a continuous or belt type rotating on the pulleys 58,anditwill be evident that when two of these brushes are employed, oneoperating in one direction and one operating in the opposite direction,the same result is secured as that when the brushes 23 and 28 are usedor when the brush 54 is used.

It will be evident that minor changes may be made in the form of themachine and in the assembling of the parts without departing from thescope of the invention.

I claim: i l

1. A machine'for finishing the edges of the brims or velour hatscomprising a hat holding means including a support "for the hat brim,abrushing mechanism to brush across the edge of the brim, and means forcausing the brushing mechanism tosucces- Zively engage adjacent portionsof the hat rim. l

I

6. A machine of the kind described comprising a hat support constructedso as to present the edge of the brim, means for rotating the hatsupport, said hat support including a cam, a brushing means, means forsupporting the brushing means so'that the brushing means operates acrossthe edge of the brim, said supporting means being in engagement With thecam, and a yielding means for holding said brushing means in engagementWith the cam.

7. A machine of the kind described com prising a hat sup-port, means forclamping the brim in said hat support so as to present the edge of thebrim for treatment, means for rotating the hat support, brushing meansincluding a shredding mechanism, carding Wires and a brush arrangedclosely adjacent to each other and rotatable in one direction, a secondbrush arranged to rotate in the opposite direction, means for rotatingthese elements in their respective directions, and yielding means forholding the said elements so that they operate across the edge of thehat brim at predetermined distances from the body of the hat.

In testimony that I claim the foregoing, I have hereto set my hand, this29th day of December, 1920.
